Aquilegia viscosa: complete guide

Overview

Aquilegia viscosa, also known as sticky columbine or Causses columbine, is an elegant alpine flower from the Cevennes in southern France. This rare gem naturally occurs in alpine and subalpine meadows of France. The plant is renowned for its exquisite blue flowers and delicate, feathery foliage.

Aquilegia viscosa is a popular choice for gardeners seeking something special and rare to add to their collection. It is seen far less commonly than its more popular relatives, making it a true treasure.

Appearance and Bloom

Aquilegia viscosa grows as an elegant, upright plant reaching 30-50 cm in height. The stems are slender and reddish at the base. The leaves are twice to thrice divided, with fine, feathery segments in a grayish-green hue.

Flowers appear from April through June and are the highlight of this plant. They feature a unique form with blue silky petals and a light yellow center. The flowers hang slightly from the stem, creating a graceful appearance. Each bloom is approximately 2-3 cm in diameter.

Ideal Location

Aquilegia viscosa thrives best in light shade to dappled shade. In southerly locations, some afternoon shade helps keep flowers fresh longer. The plant also tolerates some morning sunlight.

Plant it in borders beneath deciduous trees, against rocks, or in height-varied gardens where it receives protection from strong winds.

Soil

Aquilegia viscosa prefers well-drained, slightly acidic to neutral soils. The plant accepts sandy, clayey, and loamy soils as long as drainage is good. It grows best in soils enriched with organic matter.

Add plenty of compost when planting. The plant accepts rocky soils where many other plants would fail. Heavy clay must be improved with gravel and sand.

Watering

Aquilegia viscosa has moderate water requirements. After planting, water regularly until well-established. Once established, it accepts regular moisture but does not thrive in wet, stagnant water.

Water during dry periods, especially during the blooming season. The plant appreciates consistent moisture levels. Mulch around the base helps retain moisture.

Pruning

Aquilegia viscosa requires minimal pruning. Remove faded flowers to encourage regrowth and keep the plant tidy. After the blooming period, you can remove seed heads or leave them in place for self-seeding.

Remove dead stems in spring. The plant has a natural, elegant form that requires little trimming.

Maintenance Calendar

Spring (March-May): Remove dead stems, plant new specimens, add compost.

Summer (June-August): Deadhead faded flowers, water regularly, monitor for pests.

Autumn (September-October): Reduce watering, leave seed heads for self-seeding.

Winter (November-February): Plant dormancy, no maintenance needed.

Winter Hardiness

Aquilegia viscosa is moderately hardy in northern European climates. The plant tolerates temperatures down to approximately -10 to -15 degrees Celsius with protection. In areas with very harsh winters, shelter may be needed.

In wet winters, the plant may experience problems due to excessive moisture. Ensure excellent drainage and consider growing in pots that can be moved indoors in very severe winters.
